I have an upcoming trip from BNE-LHR via SYD and SIN later this year. Currently this is booked in O class as a roundtrip. If possible, I am keen to upgrade to a different fare (using cash) the SIN-LHR component to PE. As this is currently a round-trip, I'm thinking this may not be possible and that I need to upgrade the whole thing from BNE.
Does anyone know if it is possible to do a partial upgrade on this type of fare? Cancellation is not an option as I don't want to lose my seats on the BNE-SYD-SIN sectors. I know I can use the fare as credit, but the restriction on this being from the "point of origin" might make this difficult since I'd probably need to do an end-on-end combination to achieve what I want, and the origin of the second fare would be SIN.
Any ideas/thoughts/experiences?
Thanks
